IMO practically all the TT manufacturers out there have roughly the same build quality: so-so. They are ok, but just ok. The TT's are built cheap and light, and the seams and openings need attention on a regular basis.
I would venture to say that any of the major brands will be about equal in quality. That's why it comes down more to the layout and features you like. One notable exception IMO is the Casita (sold factory direct from Rice TX) with its molded-fiberglass body and cabinetry. These are very solid and have no roof/wall seams, thus less potential leak points. However, unless your 4 dogs are all small, a Casita probably won't work.
Some people feel that Lance, Arctic Fox and Nash are of higher quality than average, too.
We had a Rockwood for 3 years, no complaints. But over the years I keep moving to smaller and smaller trailers... just my own preference. Although size does come into play in terms of handling and in getting into small spots (like at national forest CGs).
By the way, I KNEW you were the wife when I saw the thread title. No husband would admit to being "so confused," LOL. :D
